JOHN B. BEAUVAIS, 0F HOLYOKE, MASSACHUSETTS, ASSIGNOR TO THE BEAUVAIS WATER HEATER COMPANY, OF HOLYOKE, MASSACHUSETTS, A CORPORATION OF MASSACHUSETTS.

WATERHEATING- APPARATUS.

To all whom it may concern Be it known that 1, JOHN B. BEAUVAIS, a citizen of the United States of America, and resident of Holyoke, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in Water-Heating Apparatuses, of which the following is a full, clear, and exact description.

This invention relates to an improved gas heating apparatus in which is especially comprised a gas burner having one or more circularly arranged burner tubes and especially designed to provide a circular flame or a circular flame encircled by another for the generation of intense heat from perfect combustion.

The burner is one especially suited for the heating of a boiler or water heater and es pecially an annular heater made or provided with radial studs or projections which extend outwardly and inwardly respectively from the outer and inner walls of such heater, such, for instance, as shown and described in Letters Patent of the United States granted to me Nov. 17th, 1908, No. 904,297. g I

Further objects of the invention are to increase the heating efliciency of the burner and by reason of the construction of the latter to render it susceptible of quick, easy and inexpensive manufacture, and to enable one portion of the burner to be separated and removed from another portion of the burner as occasion may require for the clearing of any of the numerous jet tubes or nipples of clogging matter.

The inventionis described in conjunction with the accompanying drawings and is set forth in the claims.

In the drawings :-Figure l is a side elevation on a comparatively small scale showing the gas burner, a yoke-shaped stand by which it is supported and an annular heater supported by the stand above the burner. Fig. 2 is a plan view as seen below the line 2-2, Fig. 1 on a larger scale. Figs. 3 and t are central vertical sectional views, on a still larger scale, as taken on the lines 3-3 and 4i, respectively on Fig. 2. Fig. 5 is a perspective view showing parts of the burner in separated relation.

Similar characters of reference indicate corresponding parts in all of the views.

Serial N 0. 741,456.

The gas burner comprises, as to one department or portion, an annular inclosed casing A provided with inner and outer circu larly arranged series of gas jet tubes or nipples at and upstanding above its top, having the axial passages therethrough of extremely slight diameter and connecting with the chamber 5 in the casing into which the gas supply pipe B is connected. The chambered casing may advantageously be of cast iron and made with vertically drilled holes,

through its upper wall in concentric circular arrangement and the jet tubes may be set in and through said holes in uniformly spaced arrangement with a tight driving fit. The burner, furthermore, comprises as to another portion or department thereof and which is separately made and separable from the jet tube provided chambered casing, inner and outer circularly and concentrically arranged sets of mixing tubes C C in number and arrangement corresponding to that of the jet tubes at.

The tubes C are of considerably greater diameter than the jet tubes and they are so united and supported as to have their lower ends above the top of the chambered casing, and they are so positioned above and relatively to the jet tubes that the passages through the latter are directed centrally into the lower ends of the tubes C having the passages of considerably. greater diameter.

As here shown, the inner and outer sets of tubes C are held by upper and lower skeletonized or spider frames D and E, preferably of cast iron and having vertical round holes drilled therethrough with uniformity of spacing and in concentric circular line,-the tubes C, preferably of brass, having driving fits through the holes in the upper and lower frames D and E, thereby making a drumlike structure.

The lower spider frame especially is made wit-h depending annular flanges (Z (Z forming downwardly opening annular channels 6 e at the under side of the ring frame E, into which, as clearly shown in Figs. 3 and 4, the jet tubes a protrude.

Certain of the jet tubes,-in the present instance, 4 in number, and examples of which are represented at f f in Fig. l, are made more bulky and higher and have shoulders g 9, located a short distance above the top wall of the chambered casing A.

The portions of these fittings f above the shoulders are of diameter corresponding to the internal diameter of the mixing tubes C; and when the spider frame-united tubes C are brought to their proximate relations to the jet tubes a, the lower ends of four of the tubes C which are at quarters engage with a close fit over the portions of the tubular plugs f and have rests or supporting bearings on the shoulders 9, thereby keeping the lower spider frame E and the lower ends of all of the tubes 0 suitably above the top wall of the chambered casing, permiting free ingress of air to within the chan nels e and thence upwardly into the tubes (3, excepting the four which have steadying engagements at their lower end portions about the upstanding tubular plugs f,- and these particular last mentioned tubes, as shown in Fig. 4:, have apertures 72., sidewise therethrough just above the top of the tubular plug f, so that thereby provision is made for. air ingress to these tubes as well as the majority of the similar tubes comprised in the circular series.

Gr represents a pipe extending vertically. through the burner, adapted for connection with a gas supply, independently of the gas supply for the chambered casing A,the upper end of this tube or pipe G being suitably equipped as a pilot burner and having its position between and in suitable proximity to tubes C of the inner and outer circular series.

Vertical holes 2' are made through the upper and lower spider frames D and E for the accommodation of the pilot burner pipe loosely therethrough, and the burner head j for the pilot light is easily removable from the upper end of the tube G, and where such tube passes upwardly through the chambered casing A, a bushing is forms a wall for the pipe accommodating opening, all as shown in Fig.3 of the drawings.

The tube sets and connecting supporting and steadying spider frame may as a unit be lifted upwardly clear and away from the a jet tube provided chambered casing, thereby enabling one to clear any of the restricted jet tube passages of obstructions which may have accumulated in one or more thereof.

As shown in Fig. 1, a stand is provided having a yoke-shaped upper portion H at the top of which is an annular frame J loosely encircling the upper drum-like portion of the burner. This annular frame has depending bolts m m, the shanks of which penetrate the perforations in outwardly extended ear-lugs of the chambered casing, the heads of such bolts having supporting engagements with the lower sides of such ear lugs,while the nuts 0 0 at the threaded upper extremities of the bolts form the means of detachably locking such bolts to the annular frame.

An annular heater for water M is represented in Fig. 1, the same being of substantially the character covered in my aforementioned already issued patent; and this is shown as supported suitably above the top of the burner by the upstanding brackets 23 t which rest on the aforementioned annular frame J, and have bolted connections with the base portion of the heater.

The burner when lighted gives circular outer and inner flames, for the consumption of the gas with perfect combustion, the outer circular flame impinging against the external wall of the heater and againstthe outwardly projecting studs thereof while the inner flame extends up within the inner openings within the heater for impingement against the internal wall of the latter and against the radial inwardly projecting studs thereof with the result that water in the heater may be brought to a suitably high temperature or steam generated therein with extreme rapidity.

While the burner described has been primarily designed for use in conjunction with an annular chambered heater of the type referred to, its use obviously is not confined thereto, for it is susceptible of highly advantageous employment in many other situations.

My invention is not to be considered as restricted to the exact details of construction described and shown, for various changes may be made within the purview of the appended claims without departure from the invention or sacrifice of the advantages thereof.
